The invention relates to a driving simulator, particularly for simulating the movements of earthbound vehicles. To take into account the special features of the movements of earthbound vehicles, the proposed driving simulator has a carrier unit that has a rigid floor platform, on which a test vehicle can be mounted. The carrier unit also includes at least one projection surface and at least one projector, and at least three movement modules, each of which has a wheel that rolls on a floor surface. The wheel can be steered, relative to the axis extending perpendicular to the floor, via a first drive, and can be driven by a respectively associated second drive.
